BRIR data set for interactive listener translation in two rooms

This BRIR data set was measured with a Kemar 45BA at 9 different positions along a defined translation line with a length of 2m in two different rooms,  a listening laboratory (T60 = 0.27s) and a seminar room (T60 = 1.0s). At each position BRIRs for a full 360° head rotation with an azimuth resolution of 4° were captured. Two Genelec 1030A loudspeakers served as the sound sources, one place in the fron of the line, one at the side. In addition, omni-directional room impulse responses were determined of the 9 positions at the center the head in both rooms.

The data set is of interest to study dynamic binaural synthesis for walking towards or past a sound source in two different room acoustical settings. The same source and receiver setup was used in both rooms, therefore the direct sound and its progress along the given translation line is similar.

本双耳房间脉冲响应（Binaural Room Impulse Response，BRIR）数据集采用Kemar 45BA人头仿真模型采集完成。实验分别在两间声学特性不同的房间内开展：一间为混响时间T60=0.27秒的听音实验室，另一间为混响时间T60=1.0秒的研讨室。沿长度为2米的预设平移轨迹，共设置9个采集位置；在每个位置上，均以4°的方位角分辨率捕获了人头完成完整360°旋转时的双耳房间脉冲响应。本次实验采用两台Genelec 1030A音箱作为声源，一台布置于轨迹前方，另一台布置于轨迹侧边。此外，还在两间实验室的9个采集位置中，以人头中心为测点，采集了全向房间脉冲响应。

该数据集可用于研究两种不同声学环境下，朝向或途经声源行走时的动态双耳合成技术。由于两间实验室采用了完全一致的声源与接收端配置，因此沿预设平移轨迹的直达声及其传播特性保持一致。
